Answer:
20/21
Step-by-step explanation:
tanC = opposite/adjacent = 20/21
Answer: the formula to find circumference is C=2times pie which is 3.14 times the radius. Radius is half of the diameter which in this case I believe would be 20 times that by 3.14 and get 62.8 then times that by two which gives you the answer of 125.6

Answer:
x < -6
Step-by-step explanation:
-5x - 8 > 22
Add 8 to both sides: -5x > 30
Divide both sides by 5: -x > 6
Divide both sides by -1 (reverse sign): x < -6
Answer:
the domain of the function are {-3/2, 3/2, 3}
Step-by-step explanation:
f(x)=2x+1
range=-2, 4, 7
f(x)=-2
or, 2x+1=-2
or, x=-3/2
f(x)=4
2x+1=4
or, x=3/2
f(x)=7
2x+1=7
or, x=3
